JOHN N. PURCELL, OF CONIFER, COLORADO, ASSIGNOR OF ONF-HALF TO JOEL S. WILSON, OF MEEKER, COLORADO.

BUCKLE.

SPECIFICATION forming part of Letters Patent No. 679,336, dated July 30, 1901. Application filed August 25,1897. Serial No. 649,519- (No model.)

To a/ZZ whom t may conc-ern:

Be it known that I, JOHN N. PURCELL, residing at Conifer, in the county of J efferson and State of Colorado, have invented a new and useful Improvement in Buckles, of which the following is a-speciiication.

The present invention relates to buckles, more particularly to that class of buckles in which a pivoted locking-tongue is slidably mounted upon the buckle-frame; and the object thereof is to provide a novel construction whereby when the tongue is arranged in operative position said tongue will be held against accidental displacement due to any back pressure on the strap secured thereby.

In order that the invention may be readily understood by those skilled in the art, the preferred forms of construction have been illustrated in the accompanying drawings and described in the following specification.

In the drawings, Figure l is a perspective view of the preferred form of buckle, show- Fig. 2 is a side elevation of the same. sectional view. form of construction.

Similar characters of reference designate corresponding parts in the several figures of 'the drawings.

The buckle comprises, essentially, two elements, a frame 10 and atongue 11, pivotally and slidably mounted upon said frame.

preferably consists of a base-plate 12, having the usual side and end loops 13 and 14 and a locking-bar 15, arranged transversely across Ione end and spaced from the face of said;

base-plate, thus forming a guide or keeper y16, through which the strap to be secured (designated A) is passed. The base-plate 12 is also provided along its side edges with parallel ears 17, which project above the face thereof upon the same side as the guide or keeper 16. These ears 17 each have a slot 18, that inclines toward the guide or keeper 16, and the ends of each slot have oifset portions 19 and 19, arranged, respectively, on opposite sides thereof, whereby substantially Z-shaped slots are formed, the odset portion 19 of the end of the slot nearest the keeper being arranged in the outer side of said slot.

`slidably connected to the frame.

Fig. 3 is a longitudinal Fig. 4 is a slightly-modified l By this construction retainingshoulders 20 are provided, which project into the slots for the purposes hereinafter described.

The tongue 11 comprises a flat plate 21, carrying a stud 22, that is arranged to engage in openings a in the strap A and having at its opposite side edges angular arm extensions 23, arranged to embrace the strap A and carrying pintles 24, that engage in the slots 18, whereby said tongue is pivotally and The free end of the plate 2l is made slightly smaller and is arranged to engage under thelockingbar 15.

In using the improved buckle one end of the strap (designated B) is secured to the base-plate in any suitable manner, but, as shown, by means of rivets which pass through the strap and base-plate and through a small wear-piece b, arranged on the under side of said base-plate. The tongue is then thrown to the position shown in dotted lines in Fig. 2, the oset portions 19a forming journals for the pintles 24, and the end of the strap A is passed through the guide or keeper 16 and under the lower edge of the plate 21. The tongue is then turned so that the stud 22 will engage in one of the openings d, and the strap is then pulled back, thus carrying the end of the plate under the locking-bar 15. At the same time the pintles 24 will ride down the inclined slots, and as they reach the The frame 10 is in the form of a sleeve and 1 ends thereof will swing laterally into the olfset portions 19 and behind the retainingshoulders 20. It will thus be seen that the tongue is securelyretained in place, as the shoulders 24 will prevent the pintles working back and allowing the end of the plate 21 disengaging from under the locking-bar 15. At the same time the construction permits the ready disengagement of thestrap, as a slight downward pressure upon the tongue will compress the straps sufliciently to free the pintles from the shoulders and permit of their retrograde movement in the slots.

In Fig. 4 is shown a slight modification, in which the tongue is provided with a plurality of holding-studs 24a, and a similar number of rows of openings are made in the strap for the reception of the same. By this construction a buckle is provided in which the IOO tongue is secured in operative position and is not liable to be accidently displaced'by the vibration or jar of the straps While in use. f

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention WillA be apparent to those skilled in the art without further description, and it Willbe under-,

stood that changes in the size, shape, propor- `tion, and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A buckle comprising a base, a transverse locking-bar spaced from s aid.base,`a pair of N ears projecting from the face of said `base and provided with longitudinal slots, retainingi shoulders projecting in to said slots contiguous to the ends of thesame which are nearest vthe locking-bar, and a pivotal tongue adapted to vengage under the locking-bar, said tongue beingprovided with pintles that operate inL saidslots and are adapted to engage behind y the shoulders When said tongue is .engaged underthe locking-bar.

2. A buckle comprisingabase, atransverse .locking-bar spaced from said base, a pair of longitudinally-disposed ears projecting from p `the face of said base and provided with slots Ithat incline toward the locking-bar, saidslots vhaving oset portions at their ends nearest the locking-bar forming retaining-shoulders, a pivotal tongue carrying a strap-engaging stud and having its free end adapted to en-` gage under the locking-bar, said tongue being provided with pintles that slide in said slots and are adapted to be seated in said offset portions behind the retaining-shoulders When the free end of the tongue is engaged under the locking-bar.

3. A buckle .comprisinga base, having opposite Z-shaped slots,.atransv-erse locking- .bar spaced from said base, and a tongue Aadapted to engage under the locking-barand having pintles .operating in saidslots.
